Environmental stability is a multifaceted concept and includes properties such as asymptotic stability, robustness, persistence, variability, elasticity and resistance. Resistance reflects the ability of a community or population to remain in a substantially unaltered state under external influence. The reverse of resistance is sensitivity. This ar...

... The soil organic matter significantly affects the diversity of soil macrofauna compared to its effect on the diversity of microfauna or mesofauna [11]. Soil macrofauna play a role in the process of decomposition and aggregation, increase soil aeration and nutrient cycling, and sustain the supply of nutrients in the long term [12]. They support the productive capacity of ecosystems through energy flows and mineralization of nutrients from various sources of organic matter as well as supporting soil function and resilience against the risks of environmental change [13]. ...
... The fine-scale structured soil patterns demonstrate ability to effect on the herb layer stratum [10]. Soil variables are able to explain both broad-scale and fine-scale spatial patterns [11]. ...
... However, C. gibelio seemed to have a stronger effect on water quality linked to increased phytoplankton biomass (chlorophyll a concentration), which suggests that habitat quality may deteriorate more at sites in which C. gibelio replaces C. carassius. Indeed, C. gibelio is known to alter the top-down control of phytoplankton by effectively removing large zooplankton species (Bondarev et al., 2019), thus affecting water transparency. Invasions of another congeneric IAS, C. auratus, can also lead to ecosystem degradation by promoting phytoplankton growth and reducing realized production in littoral zones (Richardson, Whoriskey & Roy, 1995). ...
... Empirical models have been developed from correlations and more complex statistical methods, using time series input parameters based on experimental data [13,14]. Nevertheless, soil temperature varies in one form or another according to meteorological conditions, such as air temperature and solar radiation, physical parameters of the soil such as surface albedo, water content and texture [15]. While Yanni et al. [16] evaluated the effect of temperature in different soil depths on the decomposition response under a changing climate; it was found that the activation energy is weak in the depths of the soil compared to its surface. ...
... The trees in the park plantation also have a non-linear effect on the soil penetration resistance. Plants affect the compactness of the soil [7,69]. Tree stands in a riparian mixed forest are a significant factor structuring both the herbaceous community and the spatial variation of soil physical properties [70][71][72]. ...
... Розуміння механізмів, які впливають на α-і β-різноманіття, є важливим для виявлення закономірностей динаміки регіонального біорізноманіття (Maamar et al., 2018;Negadi et al., 2018;Jamoneau, Passy, Soininen, Leboucher, & Tison-Rosebery, 2018). Патерни та причини розподілу видів надто різняться між ландшафтами (Blake & Loiselle, 2000;Heaney, 2001;Lennon, Koleff, Greenwood, & Gaston, 2001;McCain, 2004;Jankowski, Ciecka, Meyer, & Rabenold, 2009;Morante-Filho, Arroyo-Rodriguez, & Faria, 2016;Karp et al., 2018;Zhukov & Potapenko, 2017;Potapenko, Kunah, & Fedushko, 2019). ...
... Also, an increase in compactness leads to an increase in the proportion of small pores, which increases the intensity of capillary uplift of the water and thus contributes to an increase in the rate of evaporation of water from the soil surface. The recreation can have not only a direct effect on soil moisture variation, but also an indirect one [65,66]. Recreational impacts can lead to changes in the microrelief of an area, which affects the redistribution of moisture. ...
... The composition of the understory controls the growth, survival, and regeneration of the forest (Tonteri et al., 2016). Tree canopy determines the spatial patterns of soil macrofauna at different scales (Zhukov et al., 2018. The understory plants are sensitive to natural and anthropogenic influences and are indicators of the sustainability, health, and conservation status of temperate forests because of their importance to ecosystem function (Lencinas et al., 2011). ...
... We have established that such temperature patterns exist, but their characteristics do not fit into the traditional concepts of the hierarchy of oscillatory phenomena in living nature. The influence of oscillatory processes of different frequency is known: these are cycles of solar sunspot activity (Marques et al., 2015), annual cycles (circannual) (Gwinner, 1986), seasonal cycles, monthly cycles (circalunar) (Bondarev et al., 2018), half-monthly cycles (semi-lunar), tidal (circatidal) (Goto & Takekata, 2015;Raible et al., 2017), circadian cycles (Bulla et al., 2017). ...
... The environmental filters of soil macrofauna communities are driven by features of soil properties and soil regimes (Kunakh et al., 2021;. The variability of soil chemical properties determines habitat properties and the availability of nutrients to animals and chemical elements that form the protective structures of pedobionts (Rosa et al., 2015;Umerova et al., 2022;Yorkina et al., 2018;. An important aspect of the influence on soil animals is the physical properties of the soil . ...
